Title: Improvements in or relating to recoil mechanism for guns
IPC: F41A25/02
Filed: 1924-08-07
Abstract: 230,776. Bethlehem Steel Co., (Assignees of Froelich, C. H., and Miller, E. J.). March 15, 1924, [Convention date]. Recoil apparatus.-Relates to hydraulic recoil apparatus of the kind comprising two telescoping cylinders, the outer or cradle cylinder 17 being closed at its forward end and the inner cylinder 19 being closed at its rear end, the outer cylinder carrying, by means of a rod 36, a piston 35 which engages the inner cylinder. According to the invention, the run-out is checked and cushioned by pneumatic means. The inner cylinder is formed with longitudinal grooves which diminish in cross section from the rear to an intermediate part 41 where they terminate, such grooves restricting the flow of liquid past the piston. The recoil is also checked byconcentrically arranged helical springs formed in sections separated by a spacing member 46. As described in Specification 230,001, [Class 92 (ii) Ordnance], the gun barrel 12 is slidably mounted on the cradle and the recoil cylinder 19 is detachably fastened to the barrel by a mutilated screw pin 25. The front end of the cylinder 19 engages the closed end of the cylinder 17 to act as a pneumatic buffer to check the run-out. For this purpose, the air which enters progressively through ports 47, 48 during recoil is first expelled through the smaller port 47 during run-out and then trapped in the cylinder 49 to provide an air cushion.
Patent GB-715736-A (GB)
Title: Oxidation of paraffins
Filed: 1952-07-25
Abstract: In a process for the conversion of paraffins into oxygen-containing aliphatic compounds by reaction with oxygen in the liquid phase, water and the oxygen-containing compounds produced together with unchanged hydrocarbon are distilled from the reaction zone, condensed, allowed to separate into hydrocarbon and aqueous layers and while the layers are contiguous, oxygen-containing compounds are transferred from one layer to the other by passing a quantity of the hydrocarbon through the aqueous layer into the hydrocarbon layer and/or by passing water through the hydrocarbon layer into the aqueous layer, the modified hydrocarbon layer being recycled to the reaction zone.  Propane, butane, isobutane and pentane are specified paraffins.  Mixtures of paraffins may be used.  By passing water down through the hydrocarbon layer increased yields of ketones, alcohols and esters and decreased yields of acetic acid are obtained. Advantageously the water is passed through at a rate of 0.005-0.05, part by weight per minute per part by weight per minute of hydrocarbon layer separating out.  By the passage of hydrocarbon through the aqueous layer the formation of acetic acid is favoured. The amount of hydrocarbon passed upward may vary from 0.01 to 0.1 part by weight per part by weight of aqueous layer separating out. The extractant may be introduced into the desired layers by the use of spargers.  The oxygen-containing compounds are recovered from the aqueous layer.  In an example n-butane is treated with air at about 330 DEG  F. and 815 p.s.i. absolute in glacial acetic acid in the presence of chromium acetate, vapours being distilled off and condensed and water passed through the hydrocarbon layer to yield acetic acid, methyl acetate, ethyl acetate, methyl ethyl ketone and alcohols which are recovered from the aqueous layer.  A comparative experiment is also provided in which no additional extraction with water is made and an increase in the yield of acetic acid and decrease in the yield of esters, ketone and alcohols noted. Specification 709,674 is referred to.

Patent GB-364512-A (GB)
Title: Improvements in or relating to servo-motor mechanism for the operation of carillons
IPC: G10D13/08
Filed: 1931-07-01
Abstract: 364,512. Carillon mechanism. COPPENS, A., 106, Rue Marie-ThÚrÞse, Louvain, Belgium. July 1, 1931, No. 18996. Convention date, July 4, 1930. [Class 88 (ii).] In carillon mechanism with fluid-pressure servomotors, the key (or pedal) 1, air-valve 2, piston 3, and clapper 4, are connected to a member such as a floating lever AD which so combines their movements that the travels of the key and clapper are proportional, the key and clapper forces are proportional, and the mechanical work transmitted to the clapper equals that effected on the key multiplied by a factor (AC.BD/AB.CD) which is greater than unity. The key 1, normally drawn by a spring 21 against a stop 23, turns about a fixed pivot 26 and in its initial movement, to 1<1>, causes the floating lever to turn about a stop 24 lifting valve 2 and permitting access of compressed air from duct 6 to the upper side of the piston 3. During the main movement of the key, from 1<1> to 1<11>, the lever pivots about B<1>, and on the operator arresting the movement of the key, the piston gives a slight final pivoting movement to the lever about the point A<11>, carrying it to A<11> D<111> and closing the valve 2. By varying the positions of the points of attachment A, B, C, D, the factor may be varied from unity (B and C coinciding) to infinity (C and D coinciding); the touch may thus be modified or made uniform in spite of the larger mass of the clappers of the lower-toned bells. To allow all the levers to be formed as identical constructional units, they may be provided with a number of holes. The stop 24 may be adjusted to a point between B and C to avoid the feeling by the operator of an increase in resistance in the key, at the moment when the lever brings the servomotor into operation. Modifications are described employing single-acting servomotors, employing vacuum, or with the points A, B, C, D in other orders.

The valve members 6 and 21 are spring-biased in the off position. A lever 30 pivoted at 34 to the shaft 25 has a forked end 32 which bears against a shoulder 33 on the shaft 13, its other end 31 bearing on an adjustable screw 29 threaded into the valve body 1. The shaft 13 has a screw feed 14 so that rotation of the handle 7 causes axial movement of the member 6 to the open position, allowing hot water to be delivered to the aperture 5 and the outlet; at the same time a shoulder 33 on the shaft 13 engages the fork 32 and the lever 30 pivots on the end 31 to exert a pull on the inlet valve member 21 so that opening of the outlet valve results in opening of the inlet valve. To enable water at a somewhat lower temperature to be delivered, a by-pass passageway 35 controlled by a valve member operable by a handle 37 (Fig. 1, not shown) may be provided to connect apertures 3 and 4 so that some cold water may be allowed to mix with hot water passing on its way to the outlet.

Filed: 1959-06-03
Abstract: 866,466. Discharge lamps. SYLVANIA ELECTRIC PRODUCTS Inc. June 3, 1959 [June 18, 1958(2)], No. 19049/59. Class 39(1). A fluorescent electric discharge lamp includes two lead-in wires which support between them a coiled refractory wire electrode the central region of which has an electronemissive coating and the regions between this coating and the supports are coated with an insulating, refractory, firmly adhering material. The lead-in wires, of the preferred embodiment, support in addition to the cathode auxiliary anodes and a nickel shielding member, the latter being disposed between the coiled electrode and a stem press in the end of a glass envelope. The dimensions of the various elements are fully discussed. The electrode may be of the coiled-coiled-coil type, at least at its central portion. Suitable coatings of the oxides of strontium, calcium and barium with a small proportion of zirconium oxide are placed on the central portion 12, of the electrode, the parts 10, 11 being coated with insulating material such as the oxides of aluminium or titanium. The emissive layer preferably partially overlaps the insulating layer. The support rods may be housed in ceramic tubes except at the points when the rods are joined to the various electrodes. The tube may have a gas filling of 80% neon and 20% Argon, at about 1 mm. of mercury total pressure and the tube may contain sufficient mercury to yield an operating partial pressure of at least 10 microns, or the filling may comprise 15% helium and 85% argon. The electrode may be used in a purely Argon filled lamp, which does not have the auxiliary anodes, and the gas pressure may be 1 mm. of Hg. The alumina or titania is coated on to electrode by sintering at 1100‹C. or 1700‹C. respectively or by a cataphoretic method that part of the coil in which the coating is not required being temporarily coated in wax. The wax is removed and the emissive layer is then applied. Specification 863,724 and U.S.A. Specification 2,771,589 are referred to.
Patent GB-390492-A (GB)
Title: Process for producing hydrocarbons with high carbon content from hydrocarbons with low carbon content
IPC: C07C2/78
Filed: 1931-07-03
Abstract: Hydrocarbons having a high carbon content such as acetylene are produced from hydrocarbons having a low carbon content such as methane by burning the latter with oxygen or gases containing oxygen in volume sufficient to produce complete combustion, the heating period being so short, for example, a few thousandths of a second, that any subsequent action of the steam produced on the hydrocarbons of high carbon content is avoided.  The reaction may be carried out in narrow tubes or passages having an internal cross section of about from 4 to 100 sq. mm., the total length of the heating zone being at least 10 times the internal diameter of the tube.  A part of the heat necessary for effecting the reaction may be supplied by transmission from a previously heated heat carrier, the remainder of the heat being produced by partial combustion.  The heat carrier may be heated according to the regenerative system, the reaction mixture being then led through the same system.  The reaction gas on leaving the hottest zone may be suddenly cooled, for example, by the admixture of a cooled reaction gas from which the acetylene has been removed, or by using the heat for producing steam.  The oxygen or gases containing oxygen may be added to the original mixture in such quantities that the residual gas contains carbon monoxide and hydrogen approximately in the ratio 1 : 2 and is therefore suitable for the synthesis of benzine.  The sensible heat in the reaction gases may be employed for separately heating the initial gas and the oxygen, or oxygen-containing gas added.  Electrical heating means, for example, in the form of a spark gap, may be provided for initiating and maintaining the reaction.  In addition to acetylene, other hydrocarbons such as ethylene and benzol may be produced by the process.  According to examples (1) a mixture of methane and oxygen in the proportion of 2 : 1 is passed at a velocity of 105 litres per hour through a tube of Pythagoras composition of internal diameter 3 mm., the length of the reaction zone being 100 mm., at a temperature between 1150 DEG -1200 DEG  C.  The final gas, after condensation of steam, contains 9,5 per cent of acetylene, as well as hydrogen, carbon monoxide, and unchanged methane.  A light oil is also produced; and (2) coke oven gas and oxygen in the proportion of 5 : 1 are treated as before, the best yield of acetylene resulting when the temperature is 1000 DEG  C. and the heating period 8,5 thousandths of a second.  Figures of the acetylene yield employing half and double this reaction period are given.  Figures for the yield of acetylene are also given for cases where the temperature is 1600 DEG  C., and reaction times of 2,9, 6, and 12 thousandths of a second are employed.
